You're lucky to be catching an early warning. I've seen people with enzyme levels in the hundreds and thousands! Needless to say, they were sick, some miserably ill.
Time to be nice to your liver. Cut back on alcohol (if you drink), avoid tylenol (and the other acetomyphan products), eat good fats, eliminate bad fats, more fruit and veggie, less refined foods.
Flushing the liver might help reduce damage from past sins but long term, what matters is putting better fuel into the body, so it doesn't continue to suffer.
You don't have to do it all overnight. Start by eliminating or reducing the stuff that is the hardest on your liver -- alcohol and drugs. Move on, gradually avoiding bad things, adding good things. It is a lifestyle change, so doing it slowly gives your body time to adapt.
